Hi!
Sorry but i dont speak Italian! Just found your forum.
There is new and free software to Linux that can be used to capture meteror's and other sky events. It can be used in many ways and can handle multiple cameras too. As simple it is, the program captures every frame from video feed and stacks them to one image. Program works with older PC:s too, its easy to install and can have multiple tasks/camera. For more information and download here https://sites.google.com/site/linuxuhvo/
Iam using it with shared cameras with UFOCapture, and when UFOCapture misses meteor, UHVO has recorded it :-)
Cheers!
